Audacity Taking a LONG time to start up

Audacity Version: 2.3.3
OS: Pop!_OS 20.04 LTS x86_64
Kernel: 5.4.0-7634

Installed from Ubuntu repository but I have the same issue with the Flatpak version.

Problem:
Like the title says, the app is taking forever to open. This is on a high-end workstation with a very fast NVMe drive. See the attachments for a GIF of the problem. Everything seems to work fine once the app is open.

Terminal output when opening:

Any help diagnosing the problem would be greatly appreciated!

Do you have a lot of plug-ins installed?
Plug-ins can slow down the launch time a lot, especially if there are plug-ins (or other shared object files in the plug-ins path) that are not supported by Audacity.

3

I’m not using any plug-ins. This was a fresh install. The first thing I tried was to uninstall then reinstall the app. Then I tried the Flatpak version and I had the same issue. Both times it was on a fresh install with no plugins and the default settings.

4

Audacity’s plug-in path includes LADSPA, LV2 and VST plug-ins. If you have other audio production software installed, you may have plug-ins installed.

5

You’re probably right. I tried a bunch of different virtual machines to see if the problem would persist on other OSs. Fresh installs of Ubuntu and Pop OS both seemed to work fine, although Ubuntu was a noticeably faster. The problem must be coming from other software I have on my computer. Steam downloaded a bunch of stuff for Windows compatibility so maybe it has something to do with that.

Thanks for the help,

Daniel
